There are some pasta dinners that are simply comforting, and then there are recipes that feel like a warm family gathering in a bowl. Southern Rotel Chicken Spaghetti is one of those recipes. Tender shredded chicken and spaghetti are coated in a rich cheddar cream sauce, then combined with Rotel diced tomatoes and green chilies for a flavorful balance of creamy, cheesy, savory and slightly spicy.
The recipe starts with cooked chicken breast, making it especially convenient for busy evenings. The chicken is warmed in butter and olive oil with simple seasonings before being set aside. In the same skillet, garlic and Rotel tomatoes create the flavorful foundation for the sauce.
Chicken broth and heavy cream provide the liquid base, while softened cream cheese creates richness. Sharp cheddar delivers the main cheesy flavor, with mozzarella adding a smooth melt and Parmesan bringing a deeper savory finish.
Once the spaghetti is added, the sauce clings to every strand, while the Rotel tomatoes and green chilies add little bursts of flavor throughout the dish.
It’s hearty, creamy and satisfying, yet simple enough to prepare on a weeknight.

Why You’ll Love This Recipe
This chicken spaghetti has everything you want from a comforting Southern-inspired dinner.
The Rotel tomatoes and green chilies add acidity, color and gentle heat that cuts through the richness of the cheese sauce.
The chicken makes the pasta substantial enough to serve as a complete meal, while the combination of cheddar, mozzarella and Parmesan creates layers of cheesy flavor rather than relying on a single cheese.
The sauce is also incredibly creamy. Cream cheese gives it body, heavy cream adds richness and chicken broth keeps the flavor savory instead of making the sauce taste overwhelmingly heavy.
Another advantage is convenience. Since the recipe uses cooked shredded chicken, it is an excellent way to use leftover roasted chicken or prepared chicken from the refrigerator.
Everything comes together in one deep skillet after the spaghetti is cooked, making cleanup relatively easy.

Choose Your Ingredients
A few ingredient choices will help you achieve the best result.
Spaghetti: Cook it just until al dente. The pasta will spend another minute or two in the creamy sauce, so it should retain some firmness.
Cooked chicken breast: Shredded chicken works particularly well because it distributes throughout the spaghetti. Leftover roasted or poached chicken can be used.
Rotel tomatoes: Lightly drain the can before adding it. You want the tomato and green chili flavor without introducing too much excess liquid.
Sharp cheddar: This is the star cheese of the sauce. Sharp cheddar gives the dish a stronger, more distinctive flavor than mild cheddar.
Mozzarella: Mozzarella provides a smooth, creamy melt and helps give the sauce a luscious texture.
Parmesan: Freshly grated Parmesan adds salty, nutty depth and helps enrich the sauce.
Cream cheese: Softened cream cheese incorporates more easily into the warm cream and broth.
Chicken broth: Low-sodium broth gives you better control over the final salt level.
Pasta water: Reserve some before draining the spaghetti. Its starch can loosen the sauce while helping it remain creamy rather than watery.
What You Need
Pasta and Chicken
- 12 oz spaghetti
- 3 cups cooked chicken breast, shredded
- 2 tablespoons olive oil
- 3 tablespoons unsalted butter
Creamy Rotel Sauce
- 4 cloves garlic, minced
- 1 can (10 oz) Rotel diced tomatoes with green chilies, lightly drained
- 1 cup low-sodium chicken broth
- 1½ cups heavy cream
- 4 oz cream cheese, softened
- 2 cups shredded sharp cheddar cheese
- ½ cup shredded mozzarella cheese
- ½ cup freshly grated Parmesan cheese
Seasonings
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika
- ½ teaspoon Italian seasoning
- ½ teaspoon salt
- ¼ teaspoon black pepper
To Finish
- ⅓ cup reserved pasta water
- 2 tablespoons chopped fresh parsley
Step-by-Step Preparation

1. Cook the Spaghetti
Bring a large pot of generously salted water to a boil.
Add the spaghetti and cook according to the package directions until al dente.
The pasta should be tender but still have a slight bite.
Before draining, reserve ⅓ cup of pasta water.
Drain the spaghetti thoroughly and keep it nearby.
Don’t rinse the pasta. The natural starch on its surface helps the creamy cheddar sauce cling to the noodles.
2. Warm the Chicken
Heat the olive oil and 1 tablespoon of butter in a deep skillet over medium heat.
Add the shredded cooked chicken.
Sprinkle in the garlic powder, onion powder, smoked paprika, salt and black pepper.
Stir everything together and cook for approximately 2–3 minutes, just until the chicken is heated through and evenly seasoned.
Since the chicken is already cooked, there is no need to cook it for a long time.
Transfer the seasoned chicken to a plate.
3. Build the Garlic Base
Return the skillet to the stove.
Add the remaining butter.
Once melted, add the minced garlic.
Cook for about 30 seconds, stirring frequently.
The garlic should become fragrant without browning heavily.
4. Add the Rotel
Add the lightly drained Rotel diced tomatoes and green chilies.
Stir them into the garlic butter.
Cook for approximately 2 minutes.
This short cooking period allows the tomatoes and chilies to release their flavor into the butter while slightly softening.
5. Add the Broth and Cream
Pour the chicken broth into the skillet.
Then add the heavy cream.
Stir gently to combine everything.
Allow the mixture to become hot over medium heat, but avoid bringing it to a vigorous boil.
The broth provides savory depth while the cream creates the rich foundation for the cheese sauce.
6. Add the Cream Cheese
Reduce the heat to medium-low.
Add the softened cream cheese.
Stir continuously until the cream cheese melts completely into the broth and cream.
The sauce should become smooth and creamy.
If your cream cheese is still cold and firm, cut it into smaller pieces before adding it so it melts more quickly.
7. Add the Cheeses
Reduce the heat slightly.
Add the sharp cheddar, mozzarella and Parmesan in several additions.
Stir after each addition until the cheese has mostly melted before adding more.
This gradual method helps create a smoother sauce.
Continue stirring until all three cheeses are melted and the sauce is thick and creamy.
8. Add the Italian Seasoning
Sprinkle in the Italian seasoning.
Stir thoroughly.
Taste the sauce before adding any additional salt. The cheddar, Parmesan and chicken broth already contribute plenty of savory flavor.
9. Adjust the Sauce
Check the consistency.
If the sauce is very thick, add a small amount of the reserved pasta water.
Start with one or two tablespoons.
Stir well before deciding whether more is needed.
The goal is a creamy sauce that coats the spaghetti generously without becoming thin.
10. Add the Spaghetti
Place the drained spaghetti directly into the skillet.
Use tongs to turn the pasta through the cheddar sauce.
Lift and toss the spaghetti gently so the sauce coats the strands from top to bottom.
Continue until the pasta is evenly covered.
11. Return the Chicken
Add the seasoned shredded chicken back to the skillet.
Gently fold it into the spaghetti.
Make sure the chicken, Rotel tomatoes and green chilies are distributed throughout the pasta rather than remaining in one section of the skillet.
12. Warm Everything Together
Reduce the heat to low.
Allow the spaghetti to warm for another 1–2 minutes.
This gives the pasta time to absorb some of the creamy sauce while allowing the chicken to heat through completely.
Don’t cook for too long at this stage because the sauce will continue thickening.
13. Finish with Parsley
Turn off the heat.
Sprinkle the chopped fresh parsley over the pasta.
Fold some into the spaghetti or simply use it as a garnish.
14. Serve Immediately
Transfer the creamy chicken spaghetti to warm bowls or a large serving dish.
Finish with additional freshly grated Parmesan if desired.
Serve immediately while the cheddar sauce is creamy, smooth and melted.

Tips for Perfect Chicken Spaghetti
Cook the spaghetti al dente. Soft pasta can become mushy when combined with the hot sauce.
Reserve the pasta water. Even if you don’t need all of it, it gives you control over the sauce consistency.
Use softened cream cheese. It melts much more easily and helps prevent lumps.
Add the cheese gradually. This encourages a smooth sauce instead of adding everything at once.
Don’t boil the cheese sauce. Gentle heat is best after adding the dairy and cheese.
Lightly drain the Rotel. Too much tomato liquid can make the sauce thinner than intended.
Use sharp cheddar. It provides a stronger cheese flavor that stands up well to the chicken and green chilies.
Serve hot. The sauce naturally thickens as it cools.
Make It Even Better
Add Extra Garlic
If you’re a garlic lover, add another minced clove to the sauce. Fresh garlic pairs beautifully with the cheddar and Parmesan.
Add More Heat
For a spicier Southern-inspired version, add crushed red pepper flakes or a small amount of cayenne.
You can also use a hotter variety of diced tomatoes and green chilies if available.
Add Vegetables
Sautéed mushrooms, bell peppers, spinach or broccoli can easily be incorporated.
Bell peppers are particularly good with the tomatoes and green chilies.
Add a Crispy Topping
For a baked version, transfer the finished spaghetti to a baking dish and top with additional cheddar or Parmesan. Bake until the cheese is melted and lightly golden.
Use an Air Fryer for a Side
An air fryer can prepare a quick vegetable side while the spaghetti comes together. Broccoli, asparagus, green beans and zucchini all pair nicely with creamy chicken pasta. If you’re comparing equipment, looking at options marketed as the best air fryer 2026 can help when choosing a convenient everyday appliance.
Keep Your Kitchen Efficient
The main essential kitchen utensils needed are a large pasta pot, deep skillet, colander, tongs, wooden spoon and knife.
A robot pâtissier isn’t necessary for this dinner, but it can be useful if you’re making homemade rolls or a dessert to serve alongside the spaghetti.
Easy Variations
Rotel Chicken and Bacon Spaghetti
Cook crispy bacon separately, crumble it and sprinkle it into the finished pasta. The smoky bacon pairs particularly well with cheddar and green chilies.
Spicy Chicken Spaghetti
Add crushed red pepper flakes, cayenne or extra green chilies for a hotter version.
Broccoli Cheddar Chicken Spaghetti
Add cooked broccoli before folding in the spaghetti. The combination of broccoli and sharp cheddar is especially comforting.
Mushroom Chicken Spaghetti
Sauté sliced mushrooms in the skillet before adding the garlic and Rotel.
Mexican-Inspired Version
Replace the Italian seasoning with a small amount of taco seasoning and add chopped cilantro instead of parsley.
Extra-Cheesy Version
Add another handful of shredded cheddar or mozzarella just before serving.
Baked Chicken Spaghetti
Transfer the finished pasta to a greased baking dish. Top with extra cheddar and Parmesan, then bake until hot and bubbling.
Storage and Reheating
Allow leftover chicken spaghetti to cool before transferring it to an airtight container.
Store in the refrigerator for up to 3 days.
The sauce will become thicker once refrigerated because the pasta continues absorbing the creamy mixture.
For reheating, place the desired portion in a skillet over low to medium-low heat.
Add a splash of chicken broth, milk or cream.
Stir gently until the sauce loosens and becomes creamy again.
Avoid very high heat because the cheddar and cream-based sauce can separate.
If you plan to prepare this recipe for meal prep, keep a little extra broth or milk available for reheating.
Freezing is possible, but the creamy cheese sauce may change slightly in texture after thawing. For the best result, enjoy it fresh or refrigerated.
What to Serve With It
Because this chicken spaghetti is rich and hearty, fresh vegetable sides make an excellent contrast.
Try:
- Green salad
- Roasted broccoli
- Steamed green beans
- Air-fried asparagus
- Roasted zucchini
- Corn on the cob
- Garlic bread
- Fresh tomato salad
A crisp salad with a light vinaigrette is especially useful for balancing the creamy cheddar sauce.
For a more indulgent meal, serve warm garlic bread alongside the spaghetti so you can enjoy every bit of the sauce.
For dessert, a simple sweet treat followed by coffee prepared with a machine à café makes an easy ending.
Common Mistakes to Avoid
Overcooking the spaghetti: Cook only until al dente.
Boiling the cream: Keep the sauce gently heated.
Adding cheese over high heat: Moderate heat helps keep the sauce smooth.
Using cold cream cheese: Soften it first for easier melting.
Adding too much pasta water: Start with a small amount and only add more if necessary.
Over-seasoning early: Rotel, cheddar, Parmesan and broth all contribute flavor and salt.
Letting the finished pasta sit too long: The sauce thickens quickly as it cools.
